To all whom it"may concern cooling of the same,

Be it known that 1, THEODORE C. STEIMER, a citizen of the United States, residing at Buckhannon, Upshur have invented in Glass Gaththe following county inrthe State of West Virginia, certain new and useful Improvements ering and Pressing Machines, of which is a specification.

-My invention relates to the art of working plastic materials such as glass, and particularly to mechanism for gathering measured charges of molten glass and pressing articles in molds, by automatic machinery.

The objects of the invention are, to gather or take out of the melting'pot or furnace definite predetermined quantities of material so as to avoid waste in ch arging the mold; to enable the glass to be handled at its highest orany temperature; to provide for making any number oi articles of perfectly uniform weight and to accurately adjust the quantity of material used in the same; toautomatically deposit the glass in the molds and eject .the finished article thereirom;

to avoid suction in withdrawing the plunger from the mold and otherwise improve the operation thereof; to operate a number of such gatherers a'nd molds some to allow to adapt the feed of the machine tothe changing level of the glass in the pot, and gen erally improve the construction and operation of glass working-machines. These objects and other advanto hereinafter appear, are attained by the eonstruction illustrated in the accompanying drawings.

' Figure 1 is a side elevation of the complete machine, showing one of the gathering devices extended into the melting'pot and taking a charge; Fig. 2 is a front elevation, withthe gathering device in position to drop its charge in onset the molds and another in position '35 for the pressing operation; Fig. 3 is a plan view of the whole machine, in the position of the parts as in Fig. 2; Fig.3 is a detail section of the press operating cams 4 is a vertical section along the I line in Fig. '3, showing the interior construction l and Fig. 4 is a detail of the tripping dog;

At the present time it is customary to gather the charge of glass on an iron rod or punty by means of the adhesion of the glass to iron, and consequently it is necessary, aiter melting the-glass in the pot or iurnace,

to wait till it cools to a consistency at which it will adhere in'suflici'entquantity to the rod. The'materi'almust then be handled very quickly in order to deposit it in the mold beioreit becomes too stiff. The quantity deposited is usually estimated by the workmen at each separate charge, andthe residue is cut off from the rod and discarded as scrap to be remelted again.

In my apparatus the glass may be taken practically at its highest liquid state; and the exact amount needed for the mold is measured and cut oft-before removing it from the pot or furnace and delivered 'to the mold, thereby avoiding waste as well as saving time and enabling the molded article to bernade very light in weight, 'owing to the high temperature of the melted glass. I will first describe the mechanism for this operation.

In the drawings it willbe seen that I have illustrated I the machine as mounted on a portable carriage; upon 1 the base plate 17 is placed a motor 18 and suitable. up-

rights 19, 1 9 and 19 and a stationary shell 20, for the support of the mechanism. Within the shell 20 is a re volving hollow cylinder '21 which is shown more clearly in Fig. 4. At its base it is closed and provided with an inwardly turned conical socket 22,.making an airtight joint with the cone 23 on the base plate, through which compressed air is admitted by the pipe 24.- On the outside the bottomhas an extended .flange' carrying gear teeth 25 for rotation of the cylinder.- On the top of the cylinder 21 is a hollow post extension 26, ending in a hollow square box 27, closed at the top. This box 27has jointed to it on hollow trunnions 54 a set of cylinders 28, whichnormally hangin a vertical position and are provided with pistons 29 and with tubular piston rods 30. Withinthe rod 30 is a tube 31 which carries at its lower end the gathering and measuring device 32. Referring especially to Fig. 13, 14 and 15, which show this important feature of my invention in detail, it will be seen that the hollow tube 31- carries a head 32- within which is preferably threaded the casing block 32. This block is bored with a horizontal cylindrical opening, which is closed by a plate 33 held in place by pins 34, audit is provided with a renewable steel lining 35. Again within the lining there is carried a measuring block and cutter 36; mounted upon trunnions 37 as shown in Fig. 14. The block 36 is preferably, bored with a round opening 38 as 'shown in Fig. 13, and opposite to this opening there is a fiared opening 39 in the casing block 32. It will be observed that by this construction the block 36 has a knife or cutting edge around the opening 38 therein, and that by turning this block the device is closed completely and at the same time the the glass is cleanly severed. At the back of the openof melting pot or tank furnace, F.

ing device 32 down into the melting pot.

ing 33 in block 36 are a series of small holes 40 to allow the escape of the air within the measuring cup and also to allow of the admission of compressed air through tube. 31 and ports 30'shown inFig. 4, to eject the charge of glass,'-as will bedescribed later. Referring to Fig. 13 again, it will be seen that there is pivoted to the block 36 a link '41 which in turn is pivoted to a lever 42 fulcrumed in the slotted pin 43, and by a pin 44 it is engaged by the actuating rod 45 which extends upwardly through the tube 31. I

In Fig. l the cylinder 28 is shown as turned into the position to thrust the gathering device into any form that the cylinder and other devices may be turnedat any angle and that if desired a special furnace may be used with a single hole in it at any convenient point; but my machine may be used with any other common furnaces or melting pots now in use. Referring to Fig. 1 and 4 especially, and supposing the revolving supporting cylinder 21 with the head 27 to have been turned to the proper position; at the base there is provided a large traveling gear ring 46 shown in plan. in Fig. 3, which is driven by a gear 47 as will be described later, and is so placed that it comes in contact with the geared base flange of the cylinder 21 only at one point, and then leaves it, being of a much larger diameter than said cylinder flange. Inside this ring 46 it has a slot cam 48 with a raised portion indicated at 49 in Fig. 4. Connected td the top of the pivoted cylinder 28 near its trunnion is an arm 50to which is attached a rod 51, which in turn is pivoted to a sliding rod 52 traveling in a vertical slot in the outside of the cylinder 21. At the bottom of the rod 52 it has a stud carrying a roller 53 which operates in the slot cam 48. fit will be seen that when the raised portion 49 of the cam engages the roller 53, the bar 52 and link 51 will b raised, which will throw the operating cylinder 28 over into the angular position shown in Fig. 1. Referring to Fig. 4, the trunnion 54 of the cylinder 28 is hollow, and the cylindegcarries on one side a valve box 55 as shown in Fig. 5 and 5', within which operates.

a slide valve 56 to admit compressed air to either the top or bottom of the operating cylinder. For this purpose the valve has on each side a stem 57, and as will be seen in Figs. 1 and 4" there is mounted on the supporting box 27 a stationary tripping lug 58 in such a position that as the cylinder is swung over to its angular position it will strike the stem 57 of the slide valve, which will open the ports in proper manner to admit air above the piston 29 and thereby shove the gather- Before this operation it will be understood that the gathering device has been in the open position; in Fig. 4 it will be seen that when the piston rod 30 is raised, a port 30 therein is open to the air pressure in the cylinder, and communicates by slot and port 31 with the inner tube 31. This results not only in forcibly expelling the charge of glass when the measuring cup is first opened, but thereafter until the rod is thrust out in order that another charge may be taken, the air continues to blow through the small openings 40 shown in Fig. 13, thus keeping the gathering device cool.

The devices for operating the measuring cup in the gatherer are shown in Fig. 1. The inner tube 31 which carries the gatherer extends upward and entirely It will be noted' through the length of the hollow piston rod 30 and at its top it is fixed to a small plate 60, while the tube 31 fits neatly in the tube 30 and is threaded near the upper end through a sufficient length and engages a threaded gear-wheel 61, which is for a purpose pres ently to be described. The tube 31 at the top carries a small cylinder 62 which is provided with a piston attached to the rod 45 for operating the measuring cup in the gatherer. Any suitable connection, such as the coil pipes 63 may be used to convey the air from the valve box 55 to upper and lower ports in the cylinder 62. It will be seen that when air is admitted above the piston in the cylinder 62 the rod 45 will be shoved downward to close the measuring cup 36, and, when this is exhausted and pressure is admitted below the piston it will open the measuring cup. The air ports for this purpose are shifted automatically. when the gatherer is thrust down, by means of the lug 64" on the head-plate of the piston tube 30. As it descends it strikes'a lever 65 which is pivoted on the same shaft with the arm 66, and which stands over the pin 57 on the slide valve, and by means of proper ports admits the air to the under side of the piston in cylinder 62 to close the measuring cup. The opening of the cup to discharge-the glass into the mold after the operating cylinder 28 has swung back to a vertical position, isacc'omplished by the pin 57" of the slide valve 56 striking the tripping lug 58"; this admits pressure through a pipe to the underside of the piston in the cylinder 62 and opens the cup. Just at this point, asbefore explained, the ports 30" and 31 shown inFig. 4 being drawn inside the cylinder, are open and compressed air enters and quickly and forcibly discharges the glass into the mold.

In order that the successive positions of the gatherer 100 for gradually extending the feed of the supporting devices. The positions of the parts in Fig. 1 show the tube 31 entirely extended, since the glass has been taken out of the pot from full condition down'to practically the end of the supply. Referring especially to Figs. 8 and 9, the position of the inner tube 31 with respect to the outer tube 30 is determined by the position of the gear 61 on the tube 31. gear 61 on the top of tube 30 is threaded up and down the tube 31 the extension of the latter from the cylinder piston tube is greater or less. i

Meshed with the gear 61 is a beveled gear 67 supported with its shaft 68 in an upward extension of the plate I 60, and on the outer end of the shaft 68 is mounted a trip lever 69 which carries a spring pressed dog 70 en-. gaging the teeth of acircular ratchet 71- fixed on the shaft 68. From Fig. 9 it will be seen that the trip 69 hangs downward and has an inclinedface. to move the gears at each descent of the gatherer into the pot, so as to gradually feed out the tube. 31, l have provided a pin 73 mounted on an adjustable ring 74 carried on top box 27 of the central supporting column.

Each time the trip 69 descends it strikes the pin 73 and I,

thus turning the ratchet head 71'and shaft 68, causes the gear Wheel 61 to turn on the tube 31 and extends it further into the tube 30. ll 7 I The feeding device operatesto extend. the tube 21 out of the tube 30 by any distance desired, depending That is, as the 110' In order 120 on the length of the threaded portion of the tube 31. A

vices illustrated in Figs. 8 and 9; as well as the adjusting ring 74, could be entirely omitted; but the same re sult would be obtained by simply lowering the ring 74 until the pins 73 were out of register and do'not operate upon the trip 69. In order to regulate the amount of this motion given to the tube at each descent, the height of the pin 73 may be adjusted as shown clearly at the top of Fig. 4; the top of the box 27 has an upwardly extended ring 74' threaded into a movable ring 75, which latter rides on upright studs 7 5 fixed on top The inside -of the ring 74 is provided with gear teeth and engages a pinion 76 which is carried on a shaft 77 extending downward through a cast core in the box-27 (so as not to interfere with the air tight condition of the box), and it has a hand wheel 78 by which the rod and'pinion 76 may be turned in order to revolve the'ring 74 and raise or lower the ring 76 for I the purpose just described.

, The apparatus just described may be used with form of mold oLmold-carrying machines, but is specially adapted for the set of traveling molds shown,

designed to automatically cooperate with the glassgathering devices, which deposit in them an accurately measured and uniform quantity. The shaft 81 of the motor 18 carries a pinion engaging a reducing gear on shaft 81 which in turn carries a pinion which engages with the large gear wheel 83, shown in Fig. 2. This 2 wheel hasa crank 84,- which reciprocates the horizontal rack 85. For moving the mold carrying table this racli engages a pinion 86,

45. rying the teeth and loosely resting on the solid portion which is made in the form shown in section at Fig. 7, being composed of a solid portion 86fixed on its shaft 87, and a loose portion car- 86.- jThis latter has a circular rack on its flat face which is engaged by spring past 86 mayrevolve freely in one direction, but will drive the shaft 87 in the other. At the lower end of this shaft there is a pinion.88, which engages the geared 90, asshown in Fig. 10, which on its flange 89"of a ring top has the plate as may be desired. The support and guiding of the ring 90 is the same as shown in Fig. 4 for supporting the gear. ring 46, being a guide ring 79. The gear 89- also engages the base of column 21, in order to insure corresponding movements; and this column is .driven intermittently by pinion 86" entirely similar to that just described. It will be noticed that by thismotion of the rack and pinion, while the gear .83 revolves at a I constant rate, the mold-supporting ring 91 will be given an intermittent movement which is slow at starting and slow at stopping, but is rapid at the central part of i the ,motion, and that as the rack is drawn backward,

The bottom is closed by 93, which has a downwardly extending shank 94, guided in a split tube 95 and secured in the split socket the mold when finished, and I prefer to accomplish this by means of a cam 97, supported upon the base It will be understood that after the mold containing the article 99 has traveled one step allowing sufiicient cooling, at the next movementthe shank 94 is engaged by the cam 97, which enters the slots of the socket 96 and sleeve 95, and is thus pushed up into the position ically ejecting the article. ring, I attach tothe spring presser plate 102 a hollow the top of the plunger and comes in contact with it only when the plunger is down in its extreme position, as indicated at the point marked 103". in the ring and compressed air-is introduced behind the plunger. As the plunger rises, after pressing the glass in the mold, it first opens the port 103", and allows compressed air to enter between the plunger and the article. This is for the purpose of preventing the distortion of the article by suction,

out against the mold 92, leaving the article to set in perfect form. As the plunger rises still further, it will be noted that it covers the port 104, thus shutting off the inlet of air.

Also fixed on the shaft 107 is a semi-circumferential cam 113 with its flat side at right angles to the arm 112, so that as the box 110 is depressed into the position shownby dotted lines; the fiat side .of earn 113 allows this motion, by passing into the open slot 114 on the rear side (see Fig.6), until the upper side of the original position, and holds it in raised position'during half a revolution of the cam and shaft 107'.

and gatherers are out of action and cooling for a sufficient time, and for additionally cooling the gatherers, the compressed air is allowed to escape through them, as before described, or any other cooling process may be applied. From Fig. 4 it will be seen that in order to prevent the possible falling of the gatherer during this inactive period, there is provided under each cylinder a bracket 115 which is mounted on the revolving of column 21, as shown in Figs. 3 and 4.

' tion and to a proper depth.

From the above description, it will be evident that the operation is as follows. Any one of the cylinders 28 being in vertical position in front of the machine,

'and the gathering and measuring device 32 being open, the piston 29 being at thetop of its cylinder 28,

and the air pressure underneath the same also blowing through the perforations 40 of the measuring cup 36, it will be clear that as the raised portion 49 of the.

cam 48 arrives at the point of tangency to the outside of the upright column 21, the cam will engage the 'roller 53, and by means of bar 52, will give'an upward into angular position, as shown in Fig. 1. At this tripping dog 58* on the box 27, and being unyielding in this direction will push the valve over into position, to allow exhaust of the air under the piston- 29 and introduce it above the same. This will thrust the piston tube 30 downward, and the extension tube 31 having been extended to proper length by the feeding device illustrated in Fig. 8, the gatherer 32 will be thrust into the molten glass in a straight-away direc- The flared opening 39 of the casing will collect and force into the cup 36 a full measure of glass, the air therein being meantime ex- ,pelled through the openings 40 and the passages between the tube 31 and the rod 45, escaping through the openings 30*? and 31, which are now outside of the cylinder. When the head 60 is by this motion of the piston drawn down to its lowest position, the tripping dog 64 will strike the stem of the valve 56 (Fig. 5), and put it in position to introduce air through the pipe 63 to the upper side of cylinder 62, thus thrusting the rod 45 downward, and by means of the links {11, 42, closing the measuring cup 36 and shearing off the glass cleanly, taking an exact predetermined quantity of glass, which will be regulated by the-size of the opening in this interchangeable measuring cup 36. At the same timeyor immediately after, a similar dog 64 also strikes the arm 65 of the lever 66, and thrusts over the pin 57 of the main valve 56, which opens the upper end of cylinder 28 to the exhaust, and introducesair to the lower-end by means of the pipe 27. The gatherer-32 is thus drawn out of the furnace, and at this time the downward slope of cam 48operates upon the roller 53v to bring the cylinder 28 back to vertical posipoint the pin 57" of the slide valve 56 will strike the v cylinder 28 and exposed to the air pressure thcrein, a blast of air will take effect through ;the small openings 40, and forcibly expel the charge of glass into the mold 92, which is now in position under the lgatherer. f

By means of the rack 85, the mold-carrying table 91,

- same time the ports 30 31, having been drawn into 7 as well as the upright column 21 with its cylinders thereon, will be turned through a part of the circum-- ference sufiicient to bring another mold and cylinder in register for repetition of this operation just described.

When by this motion the mold 92 arrives under the I position of the plunger 100, the arm 112 onthe shaft 107 acts upon the cam shoulder 111, and thrusts'downward the box 110 and the rod 101, carrying the plungerv into the mold. This motion of the plunger is immediately preceded by the plate 102 and mold ring 103 coming into place, under pressure of the springs shown thereon, which are attached to the bottom of the cam boxing 110. The motion oftheplunger through the ring also opens the port. 104; as the" plunger immediately; rises again, the port l03 'is opened and compressed air from the pipe 105 enters between the plunger and the still pliable glass article, to keep it correctly in place against the sides of the mold, until the plunger has covered the port 104, when the plunger and ring both rise. and the 'cam 113 having engaged its curved portion with the'top of box 110, holds the illustrated, and the mold with the article remains. standing until the ne: t step of .the movement of ring 91; in this Text movement, the etc-111 94 of the valve head, 93 is engaged by the cam 97, as shown in Fig. 10, and the article is ejected'from the mold, ready to be taken off by the attendant. nfteritlie machine has started, it will be noticed that the entire action is au tomatic, and no' attention is required, except to remove the article 99 from the bottom 93, afterit is lifted out of the mold. It will beof course understood that I may employ any of the well known mechanical devices toremove the article, so that the machine needs no attendant at all.

The gathering and measuring device may be readily adjusted to suit the amount of glass. required, by simply providing a set of the cups 36, any one of which is placed in the b1ock.32 bysimply removing the p1ate'33 and the connecting pin of the link 41.

Supposing the operation of the machine to begin with the melting pot or furnace full, it will be observed that as the level falls, the machine itself automatically regulates the reach of the arms carrying the gatherer and follows this level. According to the size of the pot, the level will be lowered with different speeds, and in order to regulate the rate of the feed or alter the distance by which the extension of the tube 31 is moved at each motion, it is onlynecessary by the hand wheel 78, to adjust the height of the tripping pin 73; as it will be observed that the number of teeth by which the trip 69 turns the gear 61, will depend upon the length oiwsurface on the inclined side of the trip which is traversed-by the pin 73. Other advantages of the mechanism will readily occur to those familiar with this art. p, l 4 5 Having thus. described my invention and? illustrated its use, what I claim as newand desire to secure by V {Letters Patent is the following:
